Refer to the diagram shown below.
The given data is
mass, kg Coordinates. m
------------- -----------------
2 (0, 0)
2 (2, 0)
4 (2, 1)
Total mass, M = 2+2+4 = 8kg
Let (x,y) be the coordinates of M.
Then, taking moments about the origin, we obtain
8x = 2*0 + 2*2 + 4*2 = 12
x = 1.5 m
8y = 2*0 + 2*0 + 4*1 = 4
y = 0.5 m
Answer: (1.5, 0.5) m
Answer:
Explanation dog and wolves are not related
Fact: Through DNA analysis scientist have established the Wolf is the ancestor of the dog.
Evidence:
scientist have already answered that question that wolfs are ancestors to dogs.
Answer:
I would say B. Just because all the other options are very common in sports
Explanation:
Explanation :
An electrical circuit can be either connected in series or parallel.
Series combination: The current flowing in each resistor is the same and the equivalent resistance is given by :
Parallel combination: The voltage for all components in the parallel combination is the same. The equivalent resistance is given by :
So, our of given options the correct one is (b) because the current flowing in both the resistors is the same.
